CN105542448A 一种高性能的碳纤维增强聚酰胺复合材料及其制备方法 无效 - 驳回

一种高性能的碳纤维增强聚酰胺复合材料及其制备方法
摘要：
本发明公开了一种高性能的碳纤维增强聚酰胺复合材料，其包括按照重量百分比的如下配方：聚酰胺树脂60～85％；增韧剂3～10％；表面功能化的碳纤维10～30％。本发明的有益效果为：1、实现碳纤维表面羧基功能化，整个反应过程不会破坏碳纤维表面的结构，碳纤维的本身的力学性能不会受到任何影响，碳纤维表面羧基官能团的引入可以改善碳纤维与树脂基体之间的相容性。2、可有效的防止因热膨胀、水分扩散等因素造成的界面脱粘现象的发生，可以保证碳纤维增强聚酰胺复合材料在高温、高湿等环境下依然保持较高的力学性能保持率。
摘要（英）：

The invention discloses a high-performance carbon fiber reinforced polyamide composite material, which comprises the following components in percentage by weight: 60-85% of polyamide resin, 3-10% of flexibilizer and 10-30% of surface functionalized carbon fiber. The high-performance carbon fiber reinforced polyamide composite material has the beneficial effects that 1. the surface carboxyl functionalization of carbon fiber is realized, the surface structure of the carbon fiber is not damaged in the whole reaction process, the self mechanical property of the carbon fiber is not influenced, and the compatibility between the carbon fiber and a resin matrix can be improved by introducing the surface carboxyl functional group of the carbon fiber; and 2. the interface unsticking phenomenon caused by thermal expansion, water diffusion and other factors can be effectively prevented, and the carbon fiber reinforced polyamide composite material can be guaranteed to have high mechanical property conservation rate in an environment of high temperature and high humidity.
